Likely causes
Drought stress
Most likelyHow to tell: Leaves may turn yellow or brown at the edges before falling off, and the soil feels bone dry several inches down.
What to do: Water the tree deeply once every 7 to 14 days, ensuring the moisture reaches 12 inches deep. Apply a 3 inch layer of mulch around the base to help hold that moisture in.
Heat stress
PossibleHow to tell: The tree sheds leaves during an intense heat wave to conserve energy and reduce water loss.
What to do: Provide extra water during extreme heat to keep the root zone cool. Ensure the tree is planted in a spot that gets full sun but has enough space for air circulation.

When to worry
It is normal for a few older leaves to drop in late summer as the tree prepares for dormancy. Be concerned if the tree loses a large portion of its canopy suddenly during the spring or early summer.
Stopping it coming back
Maintain a consistent watering schedule during the first 3 years of growth to help the root system establish firmly.

Questions people ask
- Will my cherry plum grow its leaves back this year?
- If the tree loses its leaves due to heat or drought, it likely will not grow a full new set until the following spring. Focus on keeping the tree hydrated so it stays healthy for next season.
- Are aphids causing my leaf drop?
- Aphids usually cause curling and yellowing rather than immediate leaf drop. If you see them, wash them off with a strong stream of water.
